How many moles are present in 10, 0 grams of sodium hydroxide (NaOH )

Answers

Answer:0.250 mols

Explanation:

That’s the answer I got it wrong using the guy that previously wrote that the answer is 19 mols his totally wrong don’t trust him

We have that Moles that  are present in 10, 0 grams of sodium hydroxide (NaOH ) is

Moles\ NaOH =0.25moles

From the question we are told

How many moles are present in 10, 0 grams of sodium hydroxide (NaOH )

Generally the equation for the  Molar mass of sodium hydroxide is

[tex](NaOH) = (22.990 + 15.9994 + 1.008) \\\\ {(NaOH)} = 40 g/mol[/tex]

Where

Mass_{NaOH}taken = 10 g.

[tex]Moles\ NaOH =\frac{(mass of NaOH taken)}{(molar mass of NaOH)}\\\\Moles\ NaOH = \frac{10}{(40}\\\\Moles\ NaOH =0.25moles[/tex]

Therefore

Moles that  are present in 10, 0 grams of sodium hydroxide (NaOH ) is

Moles\ NaOH =0.25moles

Answer: CONDITIONS FOR HARDY

No mutations should appear in the beetle population because new alleles would change the allele frequencies

There should be random mating among beetles

There should be no natural selection on the beetle population

The population of beetles must be large enough so that genetic drift is avoided

There should be no migration of beetles into or out of the population.

fault generally occurs at a transform boundary. O A. normal OB. strike-slip O C. thrust O D. reverse ​

Answers

Answer: Read the question carefully

TRANSFORM BOUNDARIES: B. Strike-Slip

Explanation:

A reverse fault happens at convergent boundaries.

A normal fault happens at divergent boundaries

Hope this helps :)

The fault that generally occurs at a transform boundary is a strike slip. Therefore, option B is correct.

What are transform boundary and strike-slip?

A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally in opposite directions. Transform boundaries are characterized by shallow and frequent earthquakes. The most famous example of a transform boundary is the San Andreas Fault in California, which marks the boundary between the Pacific and North American plates.

"Strike-slip" is a type of fault that occurs along a transform boundary, where two tectonic plates are sliding horizontally past each other in opposite directions. In a strike-slip fault, the movement is primarily horizontal and the rocks on either side of the fault move past each other parallel to the strike (or direction) of the fault. The San Andreas Fault in California is a well-known example of a strike-slip fault.

Hence, option B is correct.

There are over 500 species of shark.

In which of the following would competition not occur?
A Rabbits grazing in a field
B Owls and foxes hunting for mice
с Daisies and dandelions growing in a lawn
D Algae and fish in a loch

Answers

Answer is D

A- competition. Rabbits both want grass so it is a competition depending on how much grass there is.

B- competition. Owls and foxes hunting mice is considered two predators hunting, competition for food again.

C. Competition. Even plants don’t get along. Most plants need sunlight to stay alive and weeds grow quickly. The weeds are more or less silently fighting over the yard to keep growing.

D. Not competition. Algae is an underwater plant that most water life tend to feed off of. In this situation the fish would be eating the plant such as how the rabbits ate the grass, there would only be competition if there was less Algae and more fish. But in this case there is Algae and one fish.
